Maybe you currently have a KN-8828P Hottop roaster, and would like to get more out of it. Maybe you are thinking of upgrading from one of your simpler models like the KN-8828, KN-8828D, or KN-8828B to the more advanced KN-8828P digital model.
So you bought an iRoast2 and your roasts are coming out too dark or too light, or feel the flavor could be better. Maybe you are generally happy, but think you could get more from the iRoast 2.
